| 摘要: |
| 为提高全额保障性收购政策下系统的经济性和稳定性以及新能源的消纳率和自供给率，以光储柴直流微电网系统为研究对象，提出了一种新型的协调控制策略。介绍了保障并网参数、优先级判断参数和市场交易参数，并将其与传统的能量控制策略结合，旨在细化系统的运行模式、实现模式的最优切换和系统的稳定运行。同时搭建了综合评价体系和对应仿真模型，对所提优化策略进行分析验证。仿真及对比结果表明：所提新型能量协调控制策略在保证系统稳定运行的前提下，新能源的自供给率提高了2%~8%，自消纳率提高了4%~57%，系统整体的运行收益提高了4%~28%。由此可得：该策略可以有效提高系统的整体运行性能，在“全额保障性收购+市场化交易”的新能源电量消纳背景下具有广泛的应用前景。 |

| Abstract: |
| To improve the economic efficiency, operational stability, and renewable energy utilization and self-sufficiency under the full guaranteed acquisition policy, this paper focuses on a PV-storage-diesel DC microgrid system and proposes a novel coordinated control strategy. It introduces grid-connection guarantee parameters, priority decision parameters, and market transaction parameters, which are integrated with traditional energy control strategies to refine system operation modes, achieve optimal mode switching, and ensure stable system operation. At the same time, a comprehensive evaluation system and corresponding simulation models are established to analyze and verify the proposed optimization strategy. Simulation and comparison results show that, while ensuring stable system operation, the proposed coordination control strategy increases renewable energy self-sufficiency by 2%~8%, enhances self-consumption by 4%~57%, and improves the overall system operating profit by 4%~28%. Therefore, it can be concluded that the proposed strategy can effectively improve the overall system operational performance and has broad application prospects in the context of renewable energy consumption under a “full guarantee acquisition + market-oriented trading” mechanism. |
